T0 whom it may concern:

Be it known that I, JOHN BALDERSON, a citizen of the United States,residing in \Vaukegan, in the county of Lake and State of Illinois, haveinvented a certain new and useful Hanger for Sliding Doors, of which thefol-. lowing is a specification.

My invention relates to devices used to suspend and swing sliding-doorsin buildings.

My invention may also be applied to doors of elevators. It isillustrated in the accompanying drawings, in,whicl1-- Figure 1, is anelevation of two slidingdoors partly closed, showing the applianceswhich constitute my invention. Fig. 2, is a detail section taken on theline 22 of Fig; 1 showing the upper hanger in elevation, secured to thedoor. Fig. 3 is a like view of the roller-bearing, or track-way, securedto the lower edge of the door or the partition taken on line 3-3 ofFig. 1. Fig. 4c is a detail section of the upper hanger secured to thedoor, taken on the line 4-4 of Fig. 2. Fig. 5 is a detail sectionof theroller bearing secured to the lower edge of the door or partition, takenon the line 5-5 of Fig. Fig. 6 is a side elevation of the cap 14. Fig.7, is a bottom plan view of the cap 14.

Like numerals refer to like parts throughout the several views.

Referring to the drawings, 7 represents the sliding doors; 8, the barspivoted in pairs at their centers, and the corresponding mem- The outerbars are secured to the inner edges of the doors and to the partitionwall, the upper ends of the outer bars being pivoted in the.

castings, 9, and 10, secured respectively to the partition, and thespring, 15, which is secured to the edge of the door, and their-lowerends being furnished with the casters, 11. The latter travel in thetrackways, 12, secured respectively to the edge of the door andpartition. The casting, 9, is formed with a slot in which the barentering it can swing inward and outward, and is secured by any suitablemeans to the edge of the partition or the wall of the building, thecenter of its pivot being in the same vertical line, with the center ofthe pivot of the caster below.

15 is a spring secured near its lower end to the edge of the door nearthe top of the same, and through its upper end, the setscrew, 16, passesinto the lug, 18, let into the top of the door. This spring and itssetscrew are used to keep the door vertical.

10 is a casting formed with a slot to permil; a lateral movement of thebar which onters it, and with a slot for the insertion of a pivotthrough the bar when in its proper position. It has also a squareopening in its outer side near its upper end, through which the cap, 14,may be passed. It has also the lugs, 10:}, formed to pass into holesprepared for them in the spring, 15. In ascrew-threaded opening throughthe top of the casting, the

set-screw, 13, is inserted. This is used together with the cap to raiseor lower the door. The cap is formed with a seat 14%; large enough topermit the free movement inward and outward of the bar. It also hasdepending lugs 14:}, each having a groove to receive an end of the pivoton which the cap rests. The casting having been secured by its lugs tothe spring, 15, the end of the bar is passed into the casting, the pivotis inserted in its place, and the cap is introduced so that it will restover the end of the bar and upon the pivot; and the set-screws, l3, and16, are adjusted as required. The track-ways, 12, have the flanges, 12%,on their inner faces, so that the pivots of the casters shall beconfined within the track-way. The trackways are open at the top so thatthe casters may be inserted therein.

In hanging a door, the casters are first inserted in their track-ways,and then the upper ends of the outer bars are secured by their pivots intheir respective castings. The set-screws are inserted and the door isadjusted by these at its proper height and angle, and is then ready foruse. It is obvious that more than two pairs of bars can be added to andused in my invention as above set forth.

The double bars as used by me are perfectly counter-balanced by anyweight which they are capable of sustaining, so that the door cannotmove except by application of extraneous force.

I therefore do not claim broadly the use of inner edge of the door atthe top of the same; every kind of pivoted bars for the purpose the lug18 let into the upper end of the door;

in question, but the set-screw 16 passing into the door and WVhat I doclaim, and desire to secure by the said lug, the cap 14; placed in thecasting 5 Letters Patent of the United States, is 10 over the end of thebar, being formed 20 The combination of a sliding door, a hanger withdependent lugs grooved to rest upon the for the same consisting of twoor more pairs pivot which secures the bar in the casting; of bars, themembers of each pair pivoted and the set-screw 13 passing through thetop together at their middle point and the corof the casting and restingupon the top of the [0 responding members of each pair pivoted to cap,substantially as and for the purposes 25 each other at one end, theslotted casting 9 specified.
